Hi all,

PLH and I were talking about obsoleting and superseding stuff, and I checked the status on the CSS-WG's Notes.
https://www.w3.org/TR/?tag=css&status=note

One that I was surprised to find there is the CSS Print Profile (https://www.w3.org/TR/css-print/). I thought we had retired it, along with all other profiles, which are indeed no longer showing in that index page.

I have not yet been able to locate the resolution where we decided to do so, but the text in the 2018 CSS Snapshot ED (still pending publication, sorry for procrastinating) agrees with my memory:

> 2.2. CSS Profiles
> 
> Not all implementations will implement all functionality defined in CSS.
> 
> In the past, the Working Group published a few Profiles, which were meant to define the minimal subset of CSS that various classes of User Agents were expected to support.
> 
> This effort has been discontinued, as the Working Group was not finding it effective or useful, and the profiles previously defined are now unmaintained.

Did we carve out an exception that I'm failing to remember for the Print Profile, or did it just slip through the cracks where we retired the others?

Speaking of which, I'll note that other profiles (https://www.w3.org/TR/css-mobile/ & https://www.w3.org/TR/css-tv/) while correctly missing from the TR index page, do not carry any indication inside the document that they are obsolete either.

Regardless of what happened previous, I think all 3 profiles should be fully obsoleted.

Another Note I did not expect to find on the TR index page is "CSS Techniques for Web Content Accessibility Guidelines 1.0" (https://www.w3.org/TR/WCAG10-CSS-TECHS/). Last published in 2000, it seems very outdated to me. Some of it still makes sense, but some assumes things that aren't true any more. Examples
* It suggests that physical units like the pt unit should only being used on medium whose physical size you know
* It claims color names to be avoided in preference to numeric colors, presumably because color names were unpredictable and you couldn't be sure you'd get good contrast
* It recommends floats and abspos as the main way to do layout, layering, and alignment

There should be better resources than this nowadays. This looks like a good candidate for obsoleting as well. It does have nice screenshots of Opera 4.01, though.
